Why does my Linkedin share button not work?

Question

I want to create a share button for Linkedin, the GUI button is all set up, but it doesn't work when clicking it. I researched a bit and came to the conclusion that using the same sharing mechanism, other sites work but mine doesn't.

I narrowed the problem down and now I'm trying to figure out why google.com works but my site doesn't. I don't use my real company website because it's personal information, but it's a website that has been on the internet for more than 10 years (in case this information is useful). When I go to the links, my website throws an error, but Google works fine.

Ⓧ　https://www.linkedin.com/cws/share/?url=https://www.my-company-website.com

〇　https://www.linkedin.com/cws/share/?url=https://www.google.com

Is there any pre-requisite I'm missing, which makes my site not work?

Answer 1

If you ever get stuck on trying to figure out why your page simply doesn't populate nice preview data on your LinkedIn share page, then check out the LinkedIn Post Inspector.

Insert the URL of your page (i.e., example.com), not the URL you are using to share (i.e., linkedin.com/share?url=example.com). You'll get detailed information on how your site will appear and why, like, for instance, sharing wikipedia.org...

Hope this helps someone else with a LinkedIn share issue!

Answer 2

As hint: I was working on closed webpage (for outside users) and that also causing problems with Linkedin share button.

Hint 2: Website uses Lets Encrypt! SSL and information mentioned here is a fake news https://wordpress.org/support/topic/linkedin-share-button-not-working-3/ Work's fine!

Answer 3

I realized my server was blocking Linkedin (to reduce traffic from Linkedin bots). That's why it wasn't working.
